Title: Intraocular lens
Inventor: KOJIMA MASANOBU
IPC: A61L27/00
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To impart antibacterial power, and permanently reveal the effect by covering a surface of an intraocular lens inserted into an eye or installed on an eyeball surface with a photocatalyst layer including a photocatalyst. SOLUTION: A lens surface of an interaocular lens is coated with a photocatalyst to impart antibacterial performance thereto by using reaction of the photocatalyst. Since photocatalyst reaction semipermanently continues as long as the photocatalyst absorbs the light, hydroxyradical is continuously generated from the intraocular lens coated with the photocatalyst, so that an antibacterial effect can be perpetuated. Titanium dioxide (TiO2) is most desirable as the photocatalyst to be used, and metallic oxide such as ZnO, SnO2, SrTiO3, WO3, BiO3 and Fe2O3 can be cited in addition. The titanium dioxide is desirably an anatase type titanium oxide crystal, a rutile type titanium oxide crystal and a mixture of anatase type and rutile type titanium oxide crystals.
